While Pope Francis has criticized the war before, this is the first time he has publicly suggested an investigation, according to excerpts from a new book.

Francis has not previously described the situation in Gaza as a genocide in public. But last year he was at the centre of a messy dispute after a meeting with a group of Palestinians at the Vatican, who insisted he had used the word with them in private, while the Vatican said he had not.
